Dear All, 

I have 6 IM modules and many IO Cards. I have just available one IM Module communication with all cards. Although I can see the other IM Modules without IO cards. I have failed Error about my some IO cards however some of them are ok. I have no communication problem about my bus connection.

Regards.

Hi,

what about the device Names? Did you assign PN-Name?

Check the following FAQ:

How do you configure and parameterize a PROFINET IO device on a SIMATIC S7 with STEP 7 V5?
